Struct AsyncGroup

pub struct AsyncGroup<'a> { /* private fields */ }

The structure that allows for the asynchronous execution of multiple functions and waits for all of them to complete.

Functions are added using the add method and are then run concurrently. The AsyncGroup ensures that all tasks finish before proceeding, optionally collecting any errors that occur.

Implementations

impl<'a> AsyncGroup<'_>

pub fn add<F, Fut>(&mut self, future_fn: F)

where F: FnOnce() -> Fut + Send + 'static, Fut: Future<Output = Result<(), Err>> + Send + 'static,

Adds an asynchronous function (a future-producing closure) to the group.

The provided function will be executed asynchronously when join_and_put_errors_into or join_and_ignore_errors is called.

Type Parameters

• F: The type of the closure, which must be FnOnce and Send + 'static.
• Fut: The type of the future returned by the closure, which must be Future<Output = Result<(), Err>> + Send + 'static.

Parameters

• future_fn: A closure that, when called, returns a future to be executed.
